How to restrict crafting....

Is there a way to restrict crafting on a server w/o using Oxide? I have just recently went over to Rust Essentials, as Oxide steadily throws LUA errors, and it get’s frustrating. BUT, now I don’t know how to restrict crafting on certain items. We have Explosives (Gel) blocked from crafting on our server (or did anyways) Is there an rcon command to block this once again?
